Analytic Definitions

•Management or Internal Audit derive insight from operational, financial, and other forms of electronic data internal or external to the organization.

•Insights can be historical, real-time, or predictive and can also be risk-focused (e.g., controls effectiveness, fraud, waste, abuse, policy/regulatory noncompliance)

Data Analytics(DA)

•Collection of audit evidence and indicators by an Internal Auditor on information technology (IT) systems, processes, transactions, and controls on a frequent repeatable, and sustainable basis.

Continuous Auditing(CA)

•Feedback mechanism used by Management to ensure that controls operate as designed and transactions are processed as prescribed. This monitoring method is the responsibility of management and can form an important element of the internal control environment.

Data Analytic Opportunities

Control Based: Clearly defined objectives that are more fact-based / black & white than the fraud & error based testing.Examples: User Access, Employee Terminated in HR but Active in SAP, Authorization Limits

Predictive / Forecasting: Uses advanced algorithms to use inputs provided by the user to predict future events. Accounts for changes in weather and other special events that may have skewed comparative period results.Examples: Sales Trends

Fraud / Error Based: Use fuzzy matching and advanced logic to identify potential fraud or errors or identify potential cash recoveries. Examples: Duplicate Payments , Duplicate Expense Claims, T&E

Reports / Summaries / Process Improvement: Summarizes the data for planning, reconciliation or sample selection.Examples: Vendor Spend, Accounts Payable by Business Unit.

Types of Data Analytics

Ad Hoc Analysis– Time consuming– Data typically supplied by IT– Up to 50% more budgeted time required– Difficult to repeat tests if not documented– Exploratory type analysis

Repeatable Analysis– More skills required than Ad Hoc testing– Pre-defined scripts created to perform same tests over and over again– More consistent and can be run more frequently– Data may be supplied, but imports are automated– Good documentation for the scripts/analytics

Copyright © 2013 Sunera LLC. 11

Types of Data Analytics

Centralized Analysis– Development, storing, and running of repeatable analytics is centralized– A single, powerful server is set up for the repeatable analytics– Data imports are all automated– Standards in place for developing tests and scripting– Source data and results are stored on server– Better security for data files and result files– Great deal of documentation on tests, scripts, data, and sample logic

Continuous Auditing– Process of performing audit related tasks in a continuous manner– Continuous risk and control assessments types of testing– Compliance (SOX) control testing– Security even monitoring

Copyright © 2013 Sunera LLC. 12

Types of Data Analytics

Continuous Controls Monitoring (CCM)– Very skilled and experienced individuals are able to script and

implement– All analytics and data imports are fully automated– No interaction from end users required– Allows for notifications to be sent to Business Unit Manager about

identified exceptions– May involve a web dashboard interface, workflow, remediation tracking,

and heat maps– Better role based security for reviewing results– May provide management with areas for improvement with internal

controls– A better likelihood of identifying fraudulent activity– Acts as a very good deterrent system

Benefits of Data Analytics

Access data from many disparate sources

Independent of the systems and people being audited

100% transaction coverage with unlimited file sizes

Read-only data access to ensure the integrity of the data

Audit trails are available to identify steps taken

Scripting/batching capabilities to capture test logic (like macros)

Very fast to run and produce results Easier to comply with the provisions

of Section 404 of the Sarbanes-Oxley Act

Close control loopholes before fraud escalates

Quantifies the impact of fraud Cost-effective Acts as a deterrent Can be automated for continuous

monitoring Provides focus based on risk and

probability of fraud Direct pointers to critical evidence Support for regulatory compliance Logs for review and evidence Scalability – Build on what you

need External Audit reliance

Data Analytics Automation Benefits

Validates effectiveness of internal controls Identifies occurrences of potential fraud Identifies transactional errors Identifies segregation of duties violations Identifies process deficiencies Utilizes a technology driven process Tests 100% of transactions as opposed to sampling Accesses data across disparate systems and geographies Provides prompt notification of control breakdowns Quantifies exposure of business risk Provides an auditable history of compliance tests and follow-up activities Enables better allocation of skilled audit/technical resources within the

organization

What Are the Challenges

Implementing change Changing culture for the organization Defining what CCM can accomplish Gathering large volumes of data in multiple applications Understanding data and processes Monitoring of manual controls Relying on reporting Implementing costs Integrating with multiple compliance frameworks and into the

existing IT environments

HOW DO YOU MAXIMIZE YOUR INVESTMENT IN CCM?

Where to Apply Data Analytics

What controls are eligible for automated testing? Electronic data is available and accessible. Access to data through an automated process is possible. Rules can be documented or captured within test logic. Internal controls and Compliance controls are eligible.

What are the ideal conditions for automated testing? Large number of controls are in place. Large volumes of data are available. Multiple systems and data sources are available. Data is at multiple locations Fraudulent activities are caught prior to a transaction reaching the end of

a process.

Data Analytics Examples

Accounts Payable Questionable invoices

Invoices without a valid P.O. Sequential invoices Vendor Invoice Formats

Duplicate invoices Multiple invoices for same item description Invoices for same amount on the same date Multiple invoices for same P.O. and date

Vendors Phantom vendors

PO BOX Test Vendor/Employee collusion One time Vendors or Vendors not used in over a year

Copyright © 2013 Sunera LLC. 31

Data Analytics — Non-Industry Specific

Purchasing Questionable purchases

P.O./invoices with amount paid > amount received Purchases of consumer items

Split purchases Similar transactions for same vendor within specific timeframe

Inflated prices Compare prices to standard price lists or to historical prices

Copyright © 2013 Sunera LLC. 32

Data Analytics — Non-Industry Specific

Purchase Cards Split purchases to avoid purchasing card limits

Purchases processed as two or more separate transactions Identified by isolating purchases from specific vendors within short

periods of time Favored vendors for kickbacks

Trend analysis to compare current transaction volumes to previous time period

Suspicious purchases Transactions that occur on weekends, holidays, or vacations Travel related charges not on travel expenditure reports

Copyright © 2013 Sunera LLC. 33

Data Analytics—Non-Industry Specific

Time and Expense Duplicate claims

Submitting claims twice Tracking “no receipt” claims

Isolate expenses without receipts and identify underlying trends through profiling techniques

Threshold reviews Track personnel exceeding thresholds

Inappropriate activity Compare expenses to travel records to ensure expenses claimed for

valid trips Trends by employee compared to peers Fuel vs Mileage claims

Fuel purchase location vs Branch location

Copyright © 2013 Sunera LLC. 34

Data Analytics Sample Logic

Duplicates– Exact Duplicate – All fields identical within investigation period– Almost Duplicate Variance, Same-Different Duplicates

• Purchase Order: Same Vendor and Similar Amount• Payments: Different Vendor Same Bank Account• Payments: Same Vendor Different Invoice Number Similar Amount• Payments: Same Vendor Same Invoice, Same Amount, Different Date• Payments: Same Vendor Name, Same Amount, Same Date, Different

Vendor ID

Copyright © 2013 Sunera LLC. 35

Data Analytics Sample Logic

Authorization Limits Single and multiple accumulated values exceeding limits Transaction amounts that exceed or are just below the authorization

limit Requisitions, Purchase Orders, Invoices, Payments

Accumulated transaction amounts that exceed the authorization limit Split Requisitions, Split Purchase Orders, Split Invoices, Split Payments

Aging Single Record Age

Days difference between Create Date and Approval Date Stale Requisitions, Stale Purchase Orders, Stale Invoices

Multiple Files Aging Retroactive PO vs. Invoice (Invoice Create Date prior to PO Create Date)

Copyright © 2013 Sunera LLC. 36

Data Analytics Sample Logic

Data Quality– Identifying fields where critical data elements deviate from expected values

and formats• Invalid ID formats, missing key values, invalid characters, invalid values• Requisitions, Purchase Orders, Invoices, Received Goods, Payments

Segregation of Duties– SOD Security Table Level

• Comparing roles within ERP security tables to a conflict matrix

– SOD at Transaction Level• Single Record Create/Modify vs. Approve

» Requisitions, Purchase Orders, Invoices, Payments

• Multiple files» Create/Modify PO vs. Create/Modify/Approve Vendor Master Update» Create/Modify PO vs. Receiver ID for Goods Received» Create/Modify PO vs. Create/Modify Invoice

Copyright © 2013 Sunera LLC. 37

Data Analytics Sample Logic

Numeric Pattern Matching Benford digital analysis: exceptions which reveal themselves as digital

anomalies. Higher than expected PO amount of $49,000, bypassing controls on amounts

over $50,000. Numeric Sequence or Gaps: exceptions which reveal themselves in a

numeric sequence or gap. Invoice Number Sequences (suspect invoices)

Transactions with even dollar amounts based on a divisor number, minimum transaction count, and threshold value. Expense Report Amounts with even dollar values

Copyright © 2013 Sunera LLC. 38

Data Analytics Sample Logic

String Pattern Matching– Name Match (% word match)

• Word exclusion lists to remove common words like: The, company, and, etc.• Invoice: Employee Vendor Name Match – (Phantom Vendor)• Invoice: Prohibited Vendors

– Address Match (Numeric or Alpha Numeric match)• Match on zip/postal code plus numeric digits from address field.• Match on alpha-numeric values from the address field (no spaces or special

characters)• Invoice: Employee Vendor Address Match – (Phantom Vendor)

– Soundslike Match (phonetic match)• SOUNDEX algorithm• SOUNDSLIKE algorithm • Payroll: similar employee names• T&E: Different expense cards assigned to employees with similar names
